Alright cool, thank you for the sound clips, I really appreciate it. Why don't people use the Y that comes with the MSDS anyway... I see a lot of people that use the MSDS headers and the sho shop Y. Bassicaly, the ideal is for the car to sound exactly as smooth and have the same note as the factory, just a little louder, I think that the headers will do that alone, but the Cats in the headers dissapearing with these new ones definitely could add to the raspiness cause the tubing is larger, and there are no cats. We'll see how it sounds... but I would like to keep the rasp completely out of the picture... so if that is there... do you replace the center muffler? I hear people say resonator... and they refer to the rear two as resonators, then some people call those mufflers and the center one a resonator. Either way, is it the rear two or the center that I would need to replace to get rid of the rasp if it's there? I would say the center, but what have you found?
